Adhesives: Test Method, Group Assignment, and Categorization Guide for High-Loading-Rate Applications

Abstract

This document provides guidance from within the Adhesives and Interfaces Research Team of the Coatings, Corrosion, & Engineered Polymers Branch (CCEPB) and the U.S. Army Research Laboratory (ARL) for initial performance-based screening evaluation and grouping priority assignments/categorization of candidate adhesives for high-loading-rate applications relevant to U.S. Army needs. 15.

Bioinspired Design Provides High‐Strength Benzoxazine Structural Adhesives

“…Accelerated aging of bonded lap joints was carried out in deionized water at 63 8 8Cf or 14 days. [31] Thea dhesive strengths of B-a and 2e increased by 58 %and 28 %to8.4 AE 1.8 MPa and 13.7 AE 0.92 MPa, respectively,w hile the bond strength of 1e remained unchanged (9.3 AE 1.4 MPa). Although water uptake was not assessed, the increase in bond strength for B-a and 2e may be due to plasticization of the cured resins by water, which has been previously reported for benzoxazine composites.…”
